Report an Issue

Found an issue with Font Awesome or one of our services? Talk to Us First! Publicly announcing a security issue could have some pretty damaging effects so please consider sharing it with us in private first. We'd rather get something fixed before it caused wide-spread damage.

Content Security Policy

Advertisement

Content Security Policy (opens new window) (CSP) is used to attempt to prevent a certain class of attacks including cross-site scripting and data injections. It functions by adding a Content-Security-Policy header to the HTTP response or by adding <meta> tags to the page. Since, by default, the SVG with JavaScript library attempts to add CSS to the <head> of the DOM it will violate a strict CSP. Follow the steps below to workaround this:

  1. Disable automatic CSS insertion.
  2. Reference the external CSS file explicitly.
  3. Remember to extract CSS from the bundle (if you've installed Font Awesome via package manager).

Example: When Hosting Font Awesome Yourself

  <html>
    <head>
      <script src="https://example.com/fontawesome/vVERSION/js/all.js" data-auto-add-css="false"></script>
      <link href="https://example.com/fontawesome/vVERSION/css/svg-with-js.css" rel="stylesheet">
    </head>
    ...
  </html>

Example: Using npm Packages fontawesome-free or fontawesome-pro

  require('@fortawesome/fontawesome-free');

  FontAwesome.config.autoAddCss = false

Example: When Using npm Packages fontawesome-svg-core

  import { config } from '@fortawesome/fontawesome-svg-core';

  // Make sure this is before any other `fontawesome` API calls
  config.autoAddCss = false

The stylesheet is included as an external file located in the @fortawesome/fontawesome-svg-core package. Find it at node_modules/@fortawesome/fontawesome-svg-core/styles.css.

Using Web Fonts with CSS?

You don't need to worry about CSP issues. These workarounds aren't needed. Party on, Wayne.
